UserMetadata Entity

As of version 1.1.0, the Unreal Engine software development kit (SDK) supports entities. Entities are SDK objects that bundle operations for a specific resource type and simplify working with PubNub application programming interfaces (APIs).

Use entities to perform common tasks without manually wiring requests. Some PubNub APIs are exposed via entities. Other operations are available on UPubnubClient (recommended) or on the UPubnubSubsystem object; see Configuration and the API reference for details.

Create UserMetadata

Use this factory method to return a local UserMetadata entity for a single user metadata object. A UserMetadata entity centralizes operations related to App Context user metadata.
